305-034-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-034-521-258 is a standard card edge connector from the 305 Series, designed for vertical panel mounting. It features 34 positions arranged in a dual-row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes female contacts with gold plating and solder pin termination. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female interface compatible with non-specified PCBs
• Low-profile insulator body constructed from thermoplastic material
• Gold-plated copper alloy contacts ensure reliable signal transmission

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify that the replacement part matches the original 305 series specifications exactly. Confirm the 34-position count and dual-row layout align with the existing PCB footprint. Ensure the 3.96 mm pitch and 1.57 mm board thickness compatibility are maintained to guarantee proper mechanical fit and electrical performance during installation.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-density connection is required for vertical panel applications. The dual-row design maximizes I/O density within a limited space. The gold plating offers superior corrosion resistance compared to tin finishes, making it suitable for environments where long-term reliability and low contact resistance are critical operational requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which provides a range of card edge solutions for various industrial and commercial applications. The series is characterized by its standardized dimensions and reliable construction. The 305-034-521-258 variant specifically addresses needs for moderate pin counts with dual-sided connectivity, fitting into broader system architectures requiring secure board-to-panel interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with identical 34-position dual-row configurations. Verify that any alternative maintains the same 0.156-inch pitch and 1.57mm board thickness tolerance to ensure interchangeability without modifying the host panel or PCB design.
